COMBINED AIR REGULATOR AND DEFLEGTOR.

Application filed August 23 T 0 (all whom 2'25 may concern.

Be it known that l, Jacon cross, a citizen of the United States,residing at St. Ansgar, in the county of lilitchell and State of Iowa,have invented certain new and useful improvements in Combined AirRegulators and Deflectors, oi which the following is a specification.

The invention relates to an attachment for use in cooking stoves, andmore particularly to the class of combined air regulators and deflectorsfor oil burning wick stoves.

The primary object of the invention is the provision of a device orattachment oi this character, wherein the same when placed within thestove relative to the air intake about the burner regulates the inflowof air and deflects the same from a direct course about the flame whenthe burner is lighted for increasing the combustion and to spread saidflame for assuring maximum heating qualities with a minimum consumptionof oil, the combustion being improved when the flame is low or high andwithout resultant smoking thereof.

Another object of the invention is the provision oi a device orattachment of this character, wherein a maximum fullness of flame isassured and the heat therefrom materially increased both in intensityand volume, the burner being maintained cool below the flame issuingtherefrom to avoid overheating oi said burner and the air admitted aboutsuch burner is deflected from a direct dra'lt upon the flame to avoidthe contracting oi the latter and thereby procuring the best results inthe use of the stove.

A further object or the invention is the provision of a device orattachment of this character, wherein the air admitted to the combustionchamber about the burner in the stove is regulated and controlled forsupplying the requisite quantity of air and directing the inflow of thesame for improving'the combustion during the use of the stove to assuremaximum heat and elimination of it still further object of the inventionis the provision of a device or attachmentof this character, wherein. itis readily applied about the burner within an oil stove and can beremoved when the occasion requires to permit the cleaning thereof orsaid stove, the device being of novel construction to regulate anddeflect the air in a proper course Specification of Letters Patent.

within the combustion chamber for a more perfect combustion.

A still further object or" the invention is the provision of a device ofthis character: which is extremely simple in construction, thoroughlyreliable and efficient in its purpose, and inexpensive to manufactureand install.

l Vith this and other objects in view, the invention consists in thefeatures of construction, combination, and arrangement of parts as willbe hereinafter fully described, illustrated in the accompanying drawingand pointed out in the claims hereuntoappended.

It is to be understood, of course, that changes, variations andmodifications may be made in the invention, such as come properly in thescope of the appended claims, without departing from the spirit of theinvention, or sacrificing any of its advantages.

In the accompanying drawing, Figure l is the fragmentary side elevationof a wick burner and chimney, for oil cooking stove, showing the collarfor supporting the chimney upon the burner, with the device constructedin accordance with the invention applied, the chimney being partlybroken away and supporting collar being in section.

Fig. 2 is a perspective view of the device removed from the chimney.

3 is a fragmentary perspective sectional view of the chimney showing aportion of the device in position therein.

.Fig. i is a fragmentary vertical sectional view showin a modified formof the device.

Fig. 5 is a view similar to Fig. 3, showing 7 a further modified form ofthe invention.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, A. designates a portion of a wickburner which of any approved form and B a portion of a chimney of aconstruction ordinarily used in oil burning wick cook stoves. Locatedwithin the burner A is the usual oil wick C above which is arranged aflame spreader D which may be of any ordinary well known construction.

The burner A has formed exteriorly thereon an annular bead constitutinga shoulder 10 for the mounting of a collar 11 thereabout to support thechimney B which at its lower end is formed with a suitable centralopening for telescopically receiving therein the V gers.

relative to the burner A and for the supporting of said collar upon thesame.

The chimney B at its end engaged with the collar 11 is formed with acircular rim '13 constituting a bottom shaped to provide an annulartrough 14 having at its inner periphery an upstanding vertical flange 15for frictional engagement with the collar 11, the rim 13 being formed atintervals with air inlet openings or apertures 16, which may be of anydesirable size to admit air about the burner A interiorly of the chimneyB.

If found desirable the collar 11 may be pro-' vided with suitableapertures or openings 17 for augmenting the admission of air into thesaid chimney.

Adapted to be located within the trough 14 in the bottom 13 of thechimney B is the attachment which comprises a split annular member 18,preferably made from sheet metal, although the same may be made from anyother material if found desirable and this member has at its upper edgea series of outturned upperly divergent deflector wings or fingers 19,each being formed with an outwardly tapered free or outer extremity 20whereby the wings or fingers adjacent each other of the series presenttherebetween substantially V shaped gaps 21 serving as air spaces orways, concentrically of said mem-" her, it being understood, of course,that the formation of the extremities 20 can be varied r can be variedso as to increase or decrease the spaced relation thereof in the outwarddivergent disposition of said wings or fin- Thevmember 18 at the end 22has one of the wings orfingers, 19, partly removed to provide a stop nib22, the latter to coact with the adjacent or underlying wing or finger19 at the other end of said member a 18 to preserve the circularformation of the member 18 when placed within the trough 14 and to holdthe ends of said member in registering overlapped relation to eachother.

, The wing or finger 19 next to the stop nib 22 is curved to provide alatch 23 for engagement with the body of the chimney B at the junctureof the bottom 13 therewith so as to hold the device properly seatedwithin the trough 14 when placed therein and to avoid any possibility ofdisplacement thereof in the trough.

- In applying the device the same is intro-- be disposed in their seriesin upperly divergent relation circumferentially about the collar 11 tolie above the air inlet openings or apertures 16 in the bottom 13 of thechimney for action upon the air entering the openings or apertures 16 todeflect said air in the direction of the outside wall of the chimney B,the air being regulated in its course from the trough 14 upwardlythrough the gaps 21 and between the wings or fingers 19 for circulationwithin the combustion chamber formed by the chimney B to effect animproved combustion and the spreading of the flame with resultantissuance of maximum heat and a minimum consumption of fuel.

The device with the wings or fingers 19 when placed within the bottom ofthe chimney B serves as a combined air regulator and deflector for theair I flowing through the openings or apertures 16 in the bottom of thechimney B to the point of combustion of the fuel and thereby properlydirect the air into the combustion chamber for effecting a materiallystronger indirect draft up a through the chimney with a resultant moreperfect combustion, and increase of heat with a minimum consumption offuel and at the same time eliminating smoke and odor issuing from thechimney;

It is clearly apparent that by the use of the device, a quicker heattransit is assured and a proper" current of cool air is maintained aboutthe burner below the point of the flamefor the cooling of said burner topreventthe overheating thereof. Furthermore the air. is properlydeflected into the combustion chamber in the chimney B to avoid directdraft therein for an improved combustion and a heat increase'withoutanyincrease in the consumption of oil when the stove is in use, 7'

In Fig. 4 of the drawing there is shown a slight modification of theinvention where in the bottom 24 of the chimney 25 for the cooking stovehasits vertical wall 26 formed with the device, the wings or fingers 27being integral with the vertical flange 26 and are constructed andarranged correspondingly to the wings or fingers 19 hereinbefore erablymade from a single length of wire,

the convolutions or coils 30 being arranged in properly spaced relationto each other and. the ends of the wire are formed with inter-fittedlinks 31 for connecting said ends together to provide the annular member29. The member 29 is adapted to be fitted within the trough 32 in thebottom 33 of the chim ney 34 as is clearly shown in Fig. 5 of thedrawing. The convolutions or coils 30 of the member 29 overlie the airinlet openings or apertures 35 in the bottom 33 of the chimney $34 toact upon the air for regulating the same and deflecting the coursethereof to the combustion chamber in the chimney for the admission ofthe air concentrically about the flame and adjacent the outside wall ofthe chimney and this member 29 operates in a manner similar to the otherforms of the device hereinbefore described.

It will be apparent that by reason of the annular shape of the member 29the coils or convolutions 30 thereof are spread apart a greater distanceat the outer periphery of the same than at its inner periphery so that agreater amount oi air passes between the coils or convolutions at theouter circun'rl erence of the member than at the inner periphery, thuscausing the air to flow with greater volume upwardly next to the body ofthe chimney 24- for action upon the flame to spread the same and thiscourse of the air has a tendency to improve the combustion in thechimney and to intensify the heat of the flame when the burner islighted.

From the foregoing it is thought that the construction and manner ofoperation of the invention will be clearly understood, and therefore, amore extended explanation has been omitted.

What is claimed is:

1. The combination with an oil burning cook stove having a burner and achimney, the same provided With air inlet openings, of an attachmentcomprising a deflector in the chimney above the air openings forretarding the direct course of air admitted through the openings anddeflecting said air into said chimney toward its side wallconcentrically of the burner.

2. An attachment of the character described comprising a circular memberadapted to be disposed over the air inlet openings in the chimney of acooking oil stove and having portions arranged relative to each otherfor efl'ecting the changing of the air course through said openings anddirecting said air adjacent to the side wall of the chimney.

3. An attachment of the character de scribed comprising a split circularmember and series of radially disposed upwardly divergent wings on saidmember and having tapered free extremities providing air gapstherebetween.

In testimony whereof I afiix my signature hereto.
